  • Plotting:
    • While a PLOT is up, it is possible to interact with individual layers to change their attributes.
      • The layers are accessible via reg.<plot_id>.layers.<layer_name>.
      • Some people like to do this every time:
        set reg.<plot_id>.layers.<layer_name>.color "red"
        Others like to pre-define a handle for the set of layers (usually just after PLOT is started) and then use that:
        set mylayers reg.<plot_id>.layers
          ...
        set mylayers.<layer_name>.color "red"
    • PLOT has a significant number of messages that it sends out. Inside a macro it is usually useful to filter them out by FID (the from ID) and then by name.
      procedure processMessage m:msg
        say "Got message name=^msg.name info=msg^info data=^msg.data"
      
        if msg.fid eqs "MYPLOT" then
          if msg.name eqs "MARK" then
            ...
    • See the PLOT explain file and the API for nxm.sys.libg.MPlot for more details.
    • See the %test_plot macro in the test area of SYS for examples.
